Title: Camera
Inventor: AIKAWA MASAAKI
IPC: G03B13/36
Filed: 1992-09-07
Abstract: PURPOSE:To allow a photographer to discriminate a focus by providing plural display means representing focusing/out of focusing of an object at a position confirmed from the camera front face and selecting while facing toward a changeover switch in the camera in which a photographing lens is moved to focus in response to a distance of an object. CONSTITUTION:When a photographer presses a release switch 20a, a switch SW1 is turned on by a 1st stage pressing to start automatic focus range finder. That is, a main CPU 13 controls a range finder IC10. A light projection circuit 6 receiving a control signal from the IC10 emits a range finding light, a light receiving circuit 8 receives a reflected light and it is sent to the IC10 as a range finding signal, the signal is converted into range finder data and they are outputted to a CPU 13. Thus, focusing/out of focusing of an object is discriminated and in the case of focusing, a lens drive circuit 2 moves an image pickup lens 1 to a position where an object image is formed onto a CCD 3. Then a light command control signal of display LEDs 16, 17 is fed from the CPU 13 to a LED display circuit 12 to implement exposure.

IPC: G01B11/00
Filed: 1997-09-03
Abstract: PROBLEM TO BE SOLVED: To provide an optical waveguide type displacement detector capable of exactly measuring a displacement quantity without receiving the influence of the inclination of a sample even when a sample is inclined with incident light. SOLUTION: The light emitted from a light source 17 propagate in a first double mode waveguide 3, is emitted from an end face 201 and is condensed to a sample surface 21 by an objective lens 20. The reflected light thereof is made incident on the position deviating from the center of the end face 202 of a second double mode waveguide and the symmetricalness of the wave front at the end face 202 is outputted from a subtraction circuit 22. On the other hand, the light emitted from the light source 18 is made incident on the position deviating from the center of the end face 202 of the first double mode waveguide in a reverse route and the symmetricalness of the wave front at the end face 201 is outputted from a subtraction circuit 23. The outputs of the subtraction circuits 22, 23 by the inclination of the sample surface 21 are reversed in codes from each other and may, therefore, be canceled by addition with an addiction circuit 24. Only the output by the displacement of the sample surface 21 may thus be outputted.

Title: Transferring device for electrophotographic copying machine
Inventor: MIYAZAKI SEIKICHI
IPC: G03G15/14
Filed: 1986-10-09
Abstract: PURPOSE:To obtain a distinct image free from toner scattering from a photosensitive body 3 by arranging a stripping lamp for removing an electrostatic latent image from the photosensitive body immediately after a transfer corotron. CONSTITUTION:The stripping lamp 32 for destaticizing the photosensitive body 3 is arranged immediately after the toner image transferring corotron 16 between said corotron and a destaticizing corotron 17. A developed image is transferred to paper 15 by the transfer corotron 16 in the transferring device, but since the paper 15 is charged with negative polarity, toner charged positive polarity is transferred to the paper 15. Since the electrostatic latent image on the photosenstive body 3 is not destaticized scattering of toner from the body 3 can be prevented. After transferring the toner to the paper 15, the electrostatic latent image on the body 3 is destaticized by light radiated from the lamp 32 through the paper 15. Consequently, the paper 15 can be efficiently stripped from the body 3 and a distinct image free from toner scattering can be obtained.

Filed: 1995-09-19
Abstract: PROBLEM TO BE SOLVED: To provide a peak-hold circuit in which a difference between a peak value of an input signal and a peak hold value is small, and an input impedance is large. SOLUTION: An input signal is delivered to a noninversion input terminal of an operational amplifier 6 after removing a D.C. component therefrom through a capacitor 12 and a resistor 13.

Title: Signal generating circuit
Inventor: HARA HIDEO
IPC: H03B28/00
Filed: 1984-11-16
Abstract: PURPOSE:To generate an AC signal which has no noise even when the generation of the signal is interrupted by impressing a signal which controls the stop of the generation of the AC signal to the control terminal of a gate circuit in a circuit utilized to generate a sine wave signal for the push tone generation of a pushbutton telephone set. CONSTITUTION:A signal KEYOFF which indicates whether a push button is pushed or not is inputted to not a shift register, but an NOR gate circuit 3, so even if the signal KEYOFF varies to a high level, the shift register 1 is not reset and the output of the NOR gate circuit 3 varies from one to zero. Consequently, a bit pattern outputted from the shift register 1 is set to 0 in order from the initial stage of the shift register 1 to the final stage when the signal KEYOFF varies from the low level to the high level. Namely, a voltage which has an intermediate amplitude between the maximum and minimum amplitudes is generated. Consequently, even if the signal KEYOFF varies from the low level to the high level, the output Vout of a D/A converter 2 rises slowly and noises are eliminated, so that the generation of a rasping pop noise is prevented.
